Uses |
Suggested addition amount: 0.1- An aryl phosphite antioxidant that can be used in polyolefin, polyester resin, ABS, PVC, etc. Provides good color improvement and thermal stability during processing and post-processing. As a high-efficiency auxiliary stabilizer and chelating agent, it is widely used in various PVC products. It can keep the product transparent and inhibit color change. At the same time, it can also increase the oxidation resistance and light and heat stability of the main stabilizer.
In addition, this product is also used in PE, PP, ABS, SBS, and other products, and can be used in the synthesis of pharmaceutical intermediates and new energy lithium-ion electrolyte industries. Suggested addition amount: 0.1-2.0%. |
